(1) Swollen neck or Goiter is a common condition in which your thyroid gland is swollen. Thyroid gland is a butterfly shaped gland found in neck.
There are multiple reasons behind it:
- Iron deficiency: People who are iron deficient can develop it
- Thyroiditis: It is an inflammation of thyroid glands.
- Grave’s disease: An autoimmune disease causing the thyroid to be overactive
- Goitrogens: External factors such as drugs, certain foods which would lead to goiter formation.
(2)Over production of growth hormone in children causes excessive growth, a condition called Gigantism. It mainly occurs due to the non-cancerous pituitary tumor.
